I need to install HVAC in a 2 story building. At this time the walls and floors are pretty much open. My only real options are propane or electric for the most part.
Have read some about the mini splits and comb heat pumps. Some of the combo heat pumps say they are quite efficient, SEER values from 16 to 27. They advertise the heat pumps now work to -20F. They advertise they would save heating/cooling costs of about 25 % over other systems in smaller units and no need necessarily for ductwork. I know one can promise anything. Just hoping some have had real world experiences with the newer high efficiency units.
My daughter has an older mini split system and does not like it for an add on room. My neighbor has a somewhat newer unit and likes it. Thoughts?
